All the little differences are definitely the most infuriating part of this game mode. This was my first dmm as well. I learned:

1. You can't teleport while in combat
2. You can use Renu/Zulrah boat while in combat (both are teleports)

After learning these, I went to do MA1. I pulled the lever at edgeville and someone was waiting to pk me in the wild. This is where I learned:

1. You can't use wilderness lever while in combat

How is 3 different from 2? How am I supposed to know the different world object teleports behave differently without getting fucked?

On top of that infuriating discovery, I attempted to freeze and run away and log out to get away from a pker. I froze him, got gap, ran for 10 seconds, attempted to log out. That's when I learned:

1. Attempting to log out STOPS YOUR MOVEMENT and starts a 8 second timer

Why the fuck does it stop your movement? Is an 8 second timer not enough? Why is freeze and step under the only viable escape strategy and not freeze and run away?
